Greetings and welcome to BYC Carol! So glad you joined us. There's a wealth of info, knowledge and experience shared in the multitude of threads. Browse around and see what interesting stuff you can find. By all means post away when the desire strikes you, especially if you have questions (provide as much detail/info as possible and pictures truly help)... With all the great folks here, generally someone will respond in no time at all. Please make yourself at home!
Chicken wire is AWEsome for keeping chickens (and rabbits) OUT of where you don't want them to be. It is useless however to keep predators from eating your chickens (or rabbits), so don' use chicken wire for that purpose... Use hardware cloth instead. I recommend the 1/2" over the 1/4" spacing as it's a heavier gauge wire. Of course chickens can fly (Some folks claim their rabbits do as well... I'm sill dubious

), so to keep them from flying over the chicken wire, it's good practice to clip the feathers on one wing. (that way they are like NASCAR drivers and go in continuous circles in one direction

). The wire can be held up by "step in" posts, or T-posts, or whatever you happen to have available really. For more permanent installation you can put up an actual fence (welded wire should be fine for just chickens) using T-posts.
Oh, if you haven't done so already, PLEASE put at least your general location in your profile. It could be very important if/when you ask for or offer help or advice. You know, climate issues and such. I recommend at least your state as most folks won't be able to figure out where if you put anything more specific (county, town, street, etc) by itself. Old folks like me

will never remember & look there first. (even though it appears to be in your name...) To add it, mouse hover over Account top right and a drop down will appear. Click on Personal Details and scan down. You'll see the spot for Location. Then go to the bottom and save changes. Thanks! Hope you enjoy the site!
